I did it a little differently. I do not know if I'm too complicated, that is, if there is a simpler way to do it, but it works. The benefit here is that it is not necessary to go through the "submit" to have the changes in the controller.
<ion-list>
<ion-list-header>
Disciplinas
</ion-list-header>
<ion-item *ngFor="let dsc of disciplinas">
<ion-label>{{ dsc.disciplina }}</ion-label>
<ion-toggle (ngModel)="slcDisc[dsc]" checked="false" (ionChange)="mudou(dsc.disciplina)"></ion-toggle>
</ion-item>
</ion-list>
<button (click)="teste()"> Final</button>
import { Component } from "@angular/core";
@Component({
selector: 'teste-tog',
templateUrl: 'teste-tog.component.html',
})
export class TestTogComponent {
disciplinas: Array<{disciplina: string}> = new Array<{disciplina: string}>();
slcDisc: Array<{disciplina: string}> = new Array<{disciplina: string}>();
constructor(){
this.disciplinas.push({disciplina: 'portugues'}, {disciplina: 'matematica'}, {disciplina: 'geografia'});
}
teste(){
console.log(this.slcDisc);
}
mudou(disciplina: string){
let indice = this.slcDisc.findIndex( (v) => {
return v.disciplina == disciplina
})
console.log(indice + ' ' + disciplina);
if ( indice == -1 )
this.slcDisc.push({disciplina: disciplina})
else
this.slcDisc.splice(indice, 1);
}
}
I only passed the discipline property for the change method but you can also pass the entire dsc object. You would only need to change the signature of the method.
